The invention is based on the object of creating a spreader, in particular for powdery fertilizers, which overcomes these disadvantages.

According to the invention, a movable spreader, in particular for powdery fertilizers with one Container, which is inclined in the lower part and a Has longitudinal slot, under which a conveyor is arranged, which the fertilizer in a distribution lock promotes, which is halved there by a distributor fed to the spreading units, brought into proposal, which is characterized in that the fertilizer conveyor is designed as a Vabenkette, under the upper run a sliding surface is arranged and that below the distributor a horizontal and left conveying screw is arranged, which is surrounded by a spreader with downwardly facing outlet slots. This falls the spreading material vertically evenly in the entire spreading width with a low fall height on the ground, so that this eliminates the above-mentioned disadvantages.

A further development of the invention consists in that the drive of the screw conveyor and the honeycomb chain from the PTO shaft of the tractor in a known manner is derived, their velocities being variable by known means, in order to reduce the spreads of fertilizer per hectare in the desired manner.

Furthermore, it is proposed according to the invention that short stub axles of the chain wheel driving the screw conveyors on both sides of the one on the car frame

attached side walls of the distribution lock with side-welded hangers with interconnection are supported by bearings and that the Aehsstumniel ending in the outer plane of the side walls is a square have recess in - .. oak one end engage the worm with a corresponding square.

It is also proposed according to the invention that the Spreading tubes have an upward-facing extension with an opening and a vertical one on the sttinseite Carry a plate with a passage opening for the square pin of the screw conveyor. So they can Spreading tubes with their screw conveyor can be easily removed.

A further development of the invention consists in that the conveyor worms can be rotated with their one pin end in a cap inserted into the spreader tube ends are stored so that no accumulation of fertilizer can occur at the end of the screw conveyor.

Finally, it is also proposed that the spreading tubes be held by a support arm that is curved in a circle below and that the support arms have a spring-loaded plunger with pressure jaws that act on the spreading tubes and that the latter rest against the pressure jaws with a stop. This initially provides a secure holder the spreading tubes with the screw conveyor. After the work is done, these can easily be removed so that there is traffic on public roads Roads is not obstructed. Should masts or the like stand in the way of the spreading operation that the driver does not has observed, there can be no damage to the
